=======================================================================
Cacti is now installed. If you intall it for the first time,
you may have to follow this steps to make it work correctly:
1. Create the MySQL database, a cacti user, and initialize:
a) CREATE DATABASE cacti;
b) Create a mysql user/password for cacti:
CREATE USER 'cacti'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
c) Add GRANTS:
GRANT ALL ON cacti.* TO 'cacti'@'localhost';
FLUSH PRIVILEGES;
d) Import the default cacti database:
mysql --database=cacti -ucacti -p < %%PREFIX%%/%%CACTIDIR%%/cacti.sql
NOTE:
* Cacti does not LOCK TABLES.
2. Edit %%PREFIX%%/%%CACTIDIR%%/include/config.php from the template
config.php.orig.
PHP requires the time zone to be explicitly set rather that rely on
the system time zone, otherwise poller complains. I added the
following line to my config.php:
date_default_timezone_set('America/Los_Angeles');
3. Add the following line to cron for %%CACTIUSER%%:
*/5 * * * * %%LOCALBASE%%/bin/php %%PREFIX%%/%%CACTIDIR%%/poller.php > /dev/null 2>&1
4. Example Apache 2.4 configuration:
LoadModule php5_module libexec/apache22/libphp5.so
<FilesMatch "\.php$">
SetHandler application/x-httpd-php
</FilesMatch>
<FilesMatch "\.phps$">
SetHandler application/x-httpd-php-source
</FilesMatch>
DirectoryIndex index.php
DocumentRoot "/usr/local/share/cacti"
Alias /cacti "/usr/local/share/cacti/"
Alias /Cacti "/usr/local/share/cacti/"
<Directory "/usr/local/share/cacti">
Require all granted
AllowOverride None
Order Allow,deny
Allow from all
</Directory>
5. Open a Cacti login page in your web browser and login with
admin/admin.
If you update cacti, open a login page and an updating process will
start automatically.
NOTEs as of 10Aug2014:
1) Cacti now better supports hier(7)
a) Cacti log files are now found under /var/log/cacti where you can
manage them using newsyslog.
b) Cacti RRD files are now found under /var/db/cacti/rra.
If you have an existing Cacti installation these paths are also
found in Cacti's SQL database and MUST be updated. These two SQL
commands should do the trick:
UPDATE settings SET value='/var/log/cacti/log' \
WHERE name='path_cactilog';
UPDATE poller_item SET rrd_path=\
REPLACE(rrd_path,'/usr/local/share/cacti/rra','/var/db/cacti/rra') \
WHERE rrd_path REGEXP '^/usr/local/share/cacti/rra';
2) The PERL paths in the Cacti PERL scripts have been updated to
/usr/local/bin.
Other Erratas:
Mount linprocfs in /compat/linux/proc will alow most scripts to work.
